[DeTomaso] efi horse power gain

[Julian Kift]

I am in the initial stages of an EFI retrofit on the GT40 with a TWM IR system. Even after getting a good deal on the TWM throttle bodies and the ECU it has cost far more than I care to tell in $$ and time (it's all the little stuff, plus the complexity of twin tanks in that application requiring a swirl pot etc.). I constantly ask myself why I didn't just buy a Weber 48IDF set up and may even still do that.

 

For the Pantera I have a Kinsler mechanical unit that I will convert to EFI and the ECU will be the DTAFAST (out of the UK), it is as capable as a MOTEC at about half the cost.
